Core Slice Controller

5G core slicing enables the creation of sub-slices in the core network and ensures delivery of required metrics like throughput, latency, resource sharing level, coverage area, etc.

The core network is the anchor for 5G network slicing, as it controls device subscriptions to network slices and user equipment (UE) network slice selection.

5G core slicing is complemented by adjacent capabilities in the transport and RAN network domains, as well as end-to-end, cross-domain slicing automation.

Creating and operating slice-based services is a highly complex process. Creating a single slice in the core network typically requires hundreds of configuration management commands across many managed objects.

Done manually, this is time-consuming and error prone. With automation, the time for slice creation is reduced by almost 90%, while also minimizing human errors.

Once the slice is up and running, automation is essential for slice modifications, to assure slice performance metrics and to assign / re-assign resources dynamically.

The Core Network Slice Subnet Management Function (C-NSSMF) enables automated network slicing in the 5G core, improving time-to-market, quality of service and reliability through less manual work.

The Nokia Core Slice Controller solution provides the 3GPP C-NSSMF for 5G core deployments from Nokia or other vendors. It offers automated slice lifecycle management capabilities designed for multi-cloud and multi-edge environments, relying on standards-based open interfaces and SDKs.
